lhis invention relates to ixminstcr looms and it is the ge yeral object of the invention to provide an improved form oi' support for the tube frames whereby the atter will move b without excessive vibration when the chains transporting them move around sprockets.

nxminster looms customarily employ a large number of tube frames each of which is provided vith a spool having variously colored tutt harming yarns wound thereon.

These tube iremos are mounted on and move with pair of spaced transporting chains which are given periodic movements by means of pair oit spro ets on the sto-called lt is present practice to provide each end of the tube frame with a tongue which c Ends between the members ot double lirn; on the transporting chain and to hold tube frame to the chain by .rome form of hook. s a result ci this construction the tube frame is permitted to move through a limited with respect to tl'xe chain and as the tube aine passes C trein one sine to the other over the center u- 'i sprocket l. will be given sudden movein As a result of this quick movement there is cc fl" able wearing on the tongues and hooks 'th occasional breakage oi the latter.

lt is an important obj ect of my present invention to prov'x "c a pivotal connection between the tube 'rame and the transporting' chain so that the tnbe frame may hang down by gravity for all oit its positions with respect to the path aio-ng which it travels. The snroc iets ant. sliaiits therefor are so move over the 'ached to the chains.

it a turther obgect oi my present i vention to prov improved loom opera iff mccnanism ich engages each tiene v 'J .e I. l L' E Ae as n reaches neary e p i "ec relative movement b ,L L etween the chain support and the tube frame so that the latter may be detached from the chain and moved toward tutt forming position. As shown herein l choose to use cup-like receptacles oiE if-shaped carriers or pockets on the tnbe fram s and the mechanism operates first to litt the fingers out of the cups and then move the tube frames laterally to a position permitting their descent to tutt forming position without interfering With the chain or any part carried thereby.

lt is 'further important object of my present invention to provide means whereby the yarn delivering tubes of the tube trame always point downwardly. I find that in usual practice long tube frames sag, sometimes with the yarn delivering tubes pointing downwardly, and at other times with the yarn delivering tubes pointing upwardly. The tube frames alternate from one of these positions to the other several times as they pass over the guide sprockets. A s a result oi this alternating sagging irst in one direction and then in the other the yarn in the tubes works back toward the spool, thus causing low rows of piles in the woven cloth. `Vith the structure set forth hereinafter the yarn tubes point downwardly or substantially so throughout their whole travel, and ii' there is any sagging o1" tube frames it is always in the same direction with respect to the yarn delivering tubes.

W ith these and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

)teferring particularly to Fig. 1 I have .shown a loom frame 10 in which is journaled a pullover shaft 11 having secured thereto a ratchet wheel 12 engaged by pull pawl 13 mounted on an arm 14 which pivots around the axis of shaft 11 and is pivotally connected to an actuating link 15. The latter is connected to lever 16 pivoted as at 17 to the loom frame. A second link 18 attached to the lever 1G is connected to a cam lever 19 so that as the latter moves up and down under influence of track cam 2O the pawl will be moved first to the right and then the left as viewed in Fig. 1.

Shaft 11 has secured thereto a pair of spro-.kets 21 one of which is shownherein. The upper portion of the loom frame 10 supports other sprockets certain of which as designated at 22 may be of relatively large diameter and mount-ed on cross shafts 23, while other of the sprockets 24 may be of less diameter. A pair of transporting chains 25 and 2G which are mounted, respectively, at the right and left hand sides of the loom are trained over the sprockets and are the means by which the tube frames 27 are supported and moved progressively through the loom to present one tube frame at a time to the fabric for the formation of the rows of tufts.

At each side ofthe loom there is a clutch 28 supported on the adjacent transferrer arm 29 by means of a pivot stud 30 on the arm and about which the clutch may rotate. A rod 31 is connected to each clutch at a point removed from the center of the stud 30. Each transferrer arm is pivoted about a supporting stud 32 and is moved by means of a rod 33 to have movements transverse of the loom or in directions parallel to the pullover shaft.

The rod 31 is connected to a rock lever 34 moving about a shaft 35 extending across the loom, said lever 34 being connected by means of link 36 to an actuating lever 37. The Alatter is pivotally connected as at 38 to a larger lever 39 which is pivoted by means of stud 40 to the frame of the loom. Stud 32 and shaft- 35 are mounted on carriers 41 which are attached as at 42 to upright rods 43 the lower ends of which are pivotally connected as at 44 to the relatively heavy levers 39. The latter is provided with a cam roll 45 which engages a cam 4G mounted on the driving shaft 47 secured thereto by means of a key 48. It is to be understood that a cam lever 39 is located at each end of the loom.

The matter t-hus far described and operation thereof is common in AXminster looms and forms no part of my present invention. The pullover pawl 13 is set forth in patent to Wyman No. 543,820 while the operation of the cross rods 33 is as set forth in patent to Smith and Skinner No. 186,374.

As previously stated the present invention relates more particularly to the connection between the tube frame and the chain and is aimed to provide a. construe tion which will obviate the quick and sudden movements of the tube frame with respect to the chain. Each of my improved chains is formed of a plurality of double links 50 between which extend single links 51. As shown particularly in Fig. 6 I provide the double link 50 with a pin 52 on which is pivotally mounted a. carrier or receiver As shown in Fig. 5 the carrier has upwardly and outwardly inclined surfaces 54 which in effect form a V-notch, said surfaces being substantially perpendicular to the vertical web 55 of the carrier.

Each end of the tube frame is provided with a chain engaging arm 56 the upper end of which is formed as shown in 5 with a. substantially horizontal portion 57 from the ends of which extend downwardly and inwardly inclined wings 58. The latter forni a v-shaped finger which fits the previously described notch in the carrier.

In forming the arm 56 I stamp the same from flat stock to the shape substantially shown in Fig. 7. The blank is formed with the two lateral wings 58 which extend from opposite sides of the horizontal portion 57, said wings being bent downwardly along the dotted lines indicated at 6G and the structure thus formed then being given a quarter bend along another line of folding 61 to provide a structure substantially the same as shown in Figs. 3, 5 and G.

t will be understood that the center of gravity of the tube frame will always bc below the axis of the carrier 55 or pin 52, with the result that the tube frames will hang downin a vertical direction from the carriers. The radius of the sprockets 22 will be such as to permit the tube frames to hang downwardly without causing interference between them and the shafts 23 on which the sprockets 22 are mounted. The tube frames are always free to hang downwardly while the chains are going around the sprockets, resulting in an easy movement of the frames.

In the particular form of my invention set forth herein it is necessary in order to move the tube frame from the chainto weaving position, first to raise the same so that the head of the arm 56 will be above the carrier and then to move `he heads laterally so that they will be out of vertical alignment with the carriers. -hose move ments are brought about through the previously desrribed clutches and transferrer arms. rlhe raising movement is accomplished by providing the cam 46 with a tappet 60 which is of sufficient length to hold the tube frame in a slightly raised position while it is being moved laterally out of vertical alignment with the car 'iers.

The lateral movement is effected through a large rocking shaft 6l mounted in bearing 62 securedto the loom frame. rlhis shaft preferably extends across the loom and has operative contact with the transferrer arms at each end of the loom. An operating arm 63 is keyed to the shaft 61 and connected by means of rod 6e to a lever 65 having a roll 66 which engages with the rocking cam 67. This Vlatter cam is keyed to the cam r vshaft 47 to rotate with the cam i6 and has a low dwell 68 which when in Contact with the roll 66 will permit the shaft 6l to be rocked in a countercloclrwise direction as viewed in Fig. 2 under influence of si ring 39. In this position the clutches are in alignment with kthe tube frame to start the removing operation. Cam 67 is provided with a rise 7 0 the effect of which is to depress the lever 65, when the cam rotates in the direction of arrow a, thereby rocking the shaft 6l in a clockwise direction as viewed in Fig. 2.

It is to be understood that each carrier arm 4l is pivotally connected to offset 7l formed in the shaft 6l and that each said offset passes between a cap 72 and a lower bearing portion 73 of the arm el. is held to arm ll by means of bolts 74, from which it will be seen that the carrier 4l and ill the parts mounted thereon are capable 75 which corresponds to a dwell 76 formeel of angular movement relative to the shaft 6l.

The cam 67 is provided with a high dwell in the cam d6, and the latter is provided with second tappet77 at the end 0f the high dwell 76, this tappet performing the reverse function of that accomplished by the first described tappet 60. y

As seen in Fig. 3 the tube frame desig- Arated generally at 27 comprises the yar spool S rotatable in a part of arm 5G above a bar B to which are secured and from which depend the tuft yarn tubcs T, the latter hanging downwardly at all times .ihrougliout the travel of the Chains around their sprockets.

From the structure herein described it is believed that the operation will be apparent. After the clutches have moved inwardly to the position shown in Fig. 2 and in dotted rlhe cap lines, Fig. 8, in engagement with the tube frames they will be raised by means of tappet 6@ and lever 39, which lift carrier il to the position shown in 8. Continued rotation of shaft i7 causes cam rise 70 on cam 67 to lower lever G5, thereby rocking shaft 6l in a right hand direction. This moves the carrier 4.1 rearwardly to the po sition shown in Fig. 9, the clutch having moved from the dotted to the full line position and the arm 5G still being raised to clear the chain carried pockets After the tube frame has been moved out of vertical alignment with the pockets, roll 45 will more down along surface 7 S to permit the tube frame to descent to the toit-forming position suown in dot and dash lines in Fig. 2, and also in Fig. l0. This latter ligure shows the progress of the clutch, the dotted lines showing the pos'tion after being raised, the dot d dash position showing the clutch moved rearwardly, and the full lines showing the clutch in low position. It is during this low position that a cam 8O engages the lev 37 to cause upward rocking of the same n i resultant endwise movement of the rods 3l to pivot the clutches about studs 30. lt is to be understood that there are two levers 341. which are secured to the shaft running across the loom.

After the tnft forming operation is completed the operation described takes place in reverse order, surface 81 raising the transferrer arms, the roll G6 meantime still remaining on the dwell (5 of the cani 67. Lever 39 will be supported by the short tappet 77 after being raised to its highest position and during this time the lowering face 82 of the cam G7 will arrive over the roll 6G and the latter will start to move upwardly under influence of spring` 69. This upward movement with consequent movement of the tube frame to cxtreme left position as viewed in nig, 2 tal-es place while the carrier arm il is supported by the tappet 77, but as soon as the heads of the transferrer arms substantial vertical alignment with the V -notch in the carriers of the chain, the roll 45 will move downwardly to theI dwell 76, thereby lowering trie tube frame so that the saine is retuiied to its starting` position.

There is part of the t latter cfear t frames move with arms 29 so that the .ie path along` which the tube the chains, whereupon pull pawl ll willy come i i action to bring another tube frame in position to go through the motions described.

ily ref-eri ig' particularly to l and 2 *l t the tubes eading action on the rane.

l and 1n extending therefrom point do y, respective of the location of the tube frame in the transportin chain and in spite of the fact that the tube frame goes over certain of the sprockets and under others. The effect of this condition is to prevent the yarn from creeping back into the yarn tubes, thereby lessening the chance for the formation of short tufts. Ben cause ot the tact that the tube trames are moved downwardly from the Chain to tutt forming position it is possible to employ the construction set 'forth herein which requires the yarn tubes to point downwardly at all time From the foregoing it willbe seen that I have provided a simple connection between the transporting chains and tube frames whereby the latter may be spared the objectionable vibration which characterizes tube frames at present in use. I believe I am the lirst to provide the form of connection set forth herein which permit-s the tube frame to be detached from the transporting chain and move toward tutt forming position, and I do not wish to be limited to the detailed constructions set forth herein. It is sutlicient for the purposes ot my present invention it means are provided to effect a relative movement on the part of the tube frame arm heads and the carriers to permit the trames to move downwardly without being interfered with by the carriers. It will .Y also be seen that I have provided improved mechanism, such for instance as the cams and rocking shafts 6l, to eliect a slight displacement ot the tube frames to permit the latter to be detached from the carriers. It

v will Jfurther be seen that the yarn tubes point will be seen that changes and moditications may be made therein by those skilled in the art without departing` from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:
